    This was certainly the case with this examination, although the examination request asked for three views only two were taken. In addition to the two initial views taken, a post reduction view was necessary to ensure the trochlea was properly seated in the trochlear notch of the ulna. Even though three views were originally requested, the technologist did not want to distress the patient any more than was necessary, so the two views taken were an anteroposterior view and a lateral view. Of course, due to the patient’s affliction these views were not taken in the standard manner. For instance, the first image taken was the lateral, which was taken with the patient seated in a wheelchair and the IR placed carefully under patient’s forearm and elbow. Also, because of the patient’s limited mobility of the extremity further accommodations needed to be made. Specifically, a slight angle was placed on the tube to ensure the proper anatomy was demonstrated and to reduce the amount of distortion. In contrast, for the anteroposterior…

    have learnt from participating and competing in this sport. This skill requires many different muscles, bones, joints and their actions. Before I perform my skill I jump over the rope twice quickly and then slowly once. To jump over the rope, I use flexion to bend my elbow joint, moving my radius and ulna in a circular motion from my elbow joint and my shoulder joint uses circumduction to bring the rope over my head. My bicep brachii allows me to flex my elbow to perform this skill. I flex both…

    Ulnocarpal Impaction Syndrome Ulnocarpal impaction syndrome is a condition in which tissue in the wrist (fibrocartilage) becomes damaged (impacted). This causes wrist pain on the side of the little finger (ulnar side). This often happens when one bone in the forearm (ulna) is longer than the other bone (radius). The ulna pushes against the wrist bones and pinches the fibrocartilage. If this condition is not treated, the fibrocartilage may eventually tear or wear away and become very painful. …

    Consider the arm. The biceps and the triceps are on two sides of the upper arm bone (humerus) and attach to the fore arm bones (radius and ulna) from the inside and outside of the elbow joint. Contraction of the bicep causes your arm to fold. Contraction of the triceps causes your arm to extend , your biceps muscle is attached to your shoulder blade at one end and to your ulna in your forearm at the other end. When the biceps contracts, it shortens and pulls the ulna toward the shoulder blade…
